Concentration is graphed‚ a straight line will result. The regression line’s equation is used to determine the concentration of an unknown solution once the percent of T has been measured. The equation of Beer’s Law (A=abc) is an efficient way of

we have learned in the lab to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed the organisms

base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although shop-bought vinegar usually measures 2.4 www.wisegeek.com/what-is-vinegar.htm fig 1 In this study we will determine the amount of acid in a vinegar sample

circumstance. Stress is caused by different factors‚ situations and pressure that are face by an individual. The situations and pressure that causes stress are known as stressors. Stress is not a sickness but it can have serious effects to the body. What causes stress depends‚ at least in part‚ on your perception of it (smith‚ et.al.2012:3). That is‚ if you are faced with a situation and you think of it negatively‚ then it will have negative effects‚ thus‚ if you look at it positively‚ then it will

Abstract: The purpose of this experiment was to isolate two unknown bacteria and perform a series of selective and differential tests to correctly identify each. After the bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

Event When World War II began there were 9 million people in concentration camps‚ when the war ended there were 3 million people. When the Japanese attacked Pearl Harbor President Ford put the japanese americans and the immigrants into internment camps because they looked like the enemy‚ the Japanese were not able to fight in the Military because they looked like the enemy.

I did‚ however‚ have my biases towards some of the concentrations‚ and had it in my mind that accounting‚ finance and CIS weren’t going to be for me. As of now I have a better understanding about what most of the concentrations are‚ and which ones I would enjoy and succeed in. The ones that stand out to me the
